I never thought celebrities were into crashing weddings we common folk have. In fact, isn't it the common folk who are trying to crash THEIR weddings?
Anyway, it appears John Travolta showed up unannounced and unexpectedly at the wedding of a young couple in Georgia.
According to reports, Travolta was in Georgia renewing his pilots license and met this young couple at a local bar. He took some picture with them there at the bar and also found out they were getting married the next day.
I can imagine the young couple saying, "Hey, John, why don't you come to our wedding tomorrow?" never thinking in a million years that he'd actually show up!
But he did, all "dressed up" in jeans, a t-shirt, and a ball hat (nice wedding attire, John).

Apparently, this is not John's first wedding crash... back in 1977, he and Robin Williams crashed a wedding. Guests thought they were impersonators!
